Patent CA-2220701-A1 (CA)
Title: Printing
Inventor: COLLINS TERENCE WILLIAM
IPC: B41C1/14
Filed: 1996-05-21
Abstract: A method of screen printing on to a hard non-absorbent substrate (1) involves using a screen (10) which has an ink permeable area (B) whose pattern corresponds to whatever is to be printed. The area B is divided into two parts (X and Y). Part X is of normal, maximum ink carrying capacity and part Y is of reduced ink carrying capacity. The ink carrying capacity of the reduced ink carrying capacity part Y is determined by the extent to which it is coated with ink/impenetrable emulsion (20), the size of the pores (18) in the screen (10) and the type of ink used. The ink carrying capacity of the part Y reduces with distance away from part X. The emulsion coating (20) may be in the form of dots (200), with the dots (200) increasing in diameter with distance away from part X. During printing, the reduced ink carrying capacity part Y is located over the edge region (E) of the substrate (1), and the substrate is printed up to but not on to its edge (6).

Title: Lateral plough
Inventor: CORDINGLEY DONALD GEORGE
IPC: E01H5/06
Filed: 1997-11-14
Abstract: The lateral plough is attached to the hitch assembly of a grader or snow plough and is used to remove selected segments of an elongated pile of gravel or snow. The plough has an arcuate blade for pushing the gravel or snow forward. A gate is attached by a hinge to the outer end of the blade for preventing the gravel or snow from exiting from the blade as the grader or plough advances. The angle of the blade may be adjusted by shortening or lengthening the effective length of a chain which extends from the outer edge of the gate to the blade.

Title: Recording/reproduction apparatus capable of exchanging information with storage apparatus mounted on recording medium assembly
Inventor: SUGIYAMA NOBUKAZU
IPC: H04N5/445
Filed: 1997-12-19
Abstract: A recording/reproducing apparatus (e.g., VTR) includes capability to exchange information with a storage apparatus such as a memory card mounted on a recording medium assembly (e.g., cassette). When the cassette is inserted into a compartment in the compartment in a VTR, a switch in the VTR is pushed by the case of the cassette, detecting the insertion of the cassette into the compartment. At that time, a signal indicating the insertion of the cassette into the compartment is supplied to a microcomputer from the switch. Notified by the signal, the microcomputer issues a command to a reader/writer, requesting the reader/writer to read out information pertaining to data recorded on the cassette from the memory card mounted on the cassette for recording the data through an antenna. With the cassette located outside the compartment, on the other hand, the microcomputer issues a command to a reader/writer, requesting the reader/writer to read out the information from the memory card through another antenna.

Title: Method of handover control in mobile radio communication realizing reduced control load
Inventor: NAKAMURA TAKEHIRO
IPC: H04W36/08
Filed: 1998-06-02
Abstract: In the method of handover control according to the present invention, when the mobile station recognizes that it has moved to an overlapping area, the mobile station notifies this fact to the network side and in response the network side sets up only a communication channel between the handover target base station and the exchange station for controlling that handover target base station, without setting up a radio channel between the handover target base station and the mobile station, while continuing the communication by not releasing the communication channel between the currently located base station and the exchange station and the radio channel between the currently located base station and the mobile station, so that it becomes possible to reduce a transmission control load for transmission between the base station and the exchange station as well as a control load for controlling the exchange station itself.

Title: Encoding technique for software and hardware
Inventor: JOHNSON HAROLD JOSEPH
IPC: G06F21/12
Filed: 1996-12-19
Abstract: An encoding technique of the invention protects software programs and hardware designs from being copied, tampered with, and its functions from being exposed. The software programs and hardware designs (collectivity called programs) thus encoded still remain executable. The encoding technique employs the concept of complexity of programs and produces proximity inversion in terms of functions contained in the programs, while preserving the behaviors.  Various embodiments are possible to achieve this encoding which includes, for example, cascading and intertwining of blocks of the programs.
